10 all whom it may concern:

Be it known that we, FRANOLSCO DE PAULA ISAURA Y FARGAS, PEDRO GARCIA Y (Joa- BERA, and Josiii BARRUFET Y VEoIANA, subjects of the King of Spain, residing at Barcelona, in the province of Catalonia and Kingdom of Spain, have invented a new and useful Improvement in Water-Pressure Regulators, of which the following is a specification.

The object we have in view is to produce a device for regulating the pressure of water in the water-pipes of a house, and maintaining a constant and even pressure at the faucets, which device will be highly sensitive in its action, and will be simple and durable in coustruction.

Our invention consists in the peculiar means employed by us to accomplish this purpose, as fully hereinafter explained and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1. is a vertical section of the regulator; Fig. 2, a detached section of a portion of the valve-case; Fig. 3, a vertical transverse section on the line 3' 3 in Fig. 2; and Fig. 4, an elevation of the Valve.

Like letters denote corresponding parts in all four figures.

The body of the regulator is composed of a vertical cylinder, A, and a horizontal chamber, B, connected with the cylinder A near the lower end thereof. The cylinder A has ascrewhead, a, at its upper end, from which the pipe 0 passes to the house-pipes. The head a has a guide, b, in which works. the upper end of the rod D of the piston E, which piston plays vertically in the cylinder A. The lower end of the piston-rod works in a guide, 0, in the lower head, (I, of the cylinder A. The piston E is somewhat smaller than the bore of the cylinder, a space, 6, being left between it and the walls of the cylinder, which space is accurately determined and made just large enough to allow of a certain flow of water into the space above the piston, and from thence to the house-pipes through the pipe 0.

To the outer end of the horizontal chamber B is secured, by a screw-joint, the cylindrical valve-case F. The inner vertical wall, f, of the valve-case is made quite thick, whileits outer vertical wall is formed by a screw-cap, g. The wall f is provided with a central horizontal passage, h, which connects the interior of the valve-case with the chamber B.

G is a pipe through which the water is received from the main or supply pipe. This pipe Gr connects with two diverging passages, t t, in the inner walhf, of the valve -case. These passages i t" are joined in one, where they connect with the pipeGon the lower side of the valve-case; but they diverge vertically and terminate on opposite sides of the passage h, being connected at those points with the interior of the valvecase by suitable ports.

H is a lever which is secured by a horizontal piv'ot in the passage it. One arm of this lever projects through the chamber B, and its end enters a slot in the piston-rod D, so that the movement of the piston E will rock the lever on its pivot. is tapered, and projects through the passage 71. a shortdistauce into the valve-case F. Upon this end of the lever is hung loosely a valve, I, the point of the lever entering a slot, 70, in the face of the valve. The valve I is preferably a flat metallic disk, which plays vertically in the valve-case. it has a stud, l, on its back, which strikes the capg,and prevents the valve from working off of the point of the lever H. Centrally below the slot 70 the valve has an opening, at, made through it. The valve is not intended to be held close against its seat, but is intended to play free, leaving a space, a, most of the time between its face and the wallf.

In use, the parts being in the position shown in Fig. 1, the water will flow through the pipe G into the passage t' i, and from them into the valve case around the sides of the valve. When the valvecase becomes sufficiently full the water will flow into the passage it partly through the opening at and partly through the space a. The water will fill the chamberB and cylinder A, passing around the piston, and will pass out of the pipe 0. When the pressure is increased beyond the desired degree the piston E will be raised and the valve I lowered. This movement lowers the opening at The other end of the lever below the passage h and out of line therewith, and the water can then only flow to the passage h through the space M. The supply of water to the chamber B will thus be diminished, but not entirely out off. When the pressure in the chamber B and cylinder A is again reduced the piston will drop down and the valve will be raised to the position shown in Fig. 1.

Instead of having the valve hung entirely at the end of the lever H, it can be loosely pivoted eccentrically on a pin, 1), (shown in dotted lines in Fig; 2.) Vhen hungin this manner the valve is worked eccentrically by the lever instead of being moved in a direct vertical line.

What we claim as our invention is -1. In a waterpressure regulator, the combination, with the vertical cylinder, having a piston working therein, around the sides of which the water flows to the exit, of a valve connected with such piston by a pivoted lever and operated by the movement of the piston, substantially as described and shown.

2. In a water-pressure regulator, the combination, with vertical cylinder A and horizontal chamber B, of the piston E, around which the water flows, the piston-rod D, pivoted lever H, and loose valve I, substantially as described and shown.

3. In a water-pressure regulator, the combination, with cylinder A, chamber B, piston E, around which the water passes, and rod D, of the valve-case I pipe Gr, passages i, i, and h, the pivoted lever H, and the loose valve I, having opening m, substantially as described and shown.

This specification signed and witnessed this 28th day of February, 1881.
